Leading European battery storage developer Sonnen has announced it will soon launch its Sonnenbatterie product in Australia, joining a host of international and local brand names, including Tesla, LG, Enphase, Panasonic, Samsung, Redflow and Ecoult in tapping into the first big domestic battery storage market in the world.

sonnenThe German-based Sonnen, which makes lithium-ion battery storage systems, says it will partner with True Value Solar – the biggest installer in Australia – to offer an all-in-one system of rooftop solar panels and the SonnenBatterie.

It also expects to introduce peer-to-peer trading, meaning that households with battery storage will be able to trade energy with neighbours. It has already introduced such a product into Europe.

Sonnen says it expects to expand its number of installer partnerships in Australia. Its modular battery storage systems will allow consumers to choose sizes raging from 2kWh to 16kWh

In comparison to most other suppliers it integrates the battery modules, the inverter, a smart energy manager and the measurement and communication technology in one package, making it easy to install and being very space- efficient. sonnen expects to expand its number of installer partnerships in Australia.

It expects the optimum size for the average household would be 8-10kWh. It says a system of this capacity can save several hundreds of dollars a year in power costs.

“Australians are excited about the opportunities for self-consumption and energy storage right now,” Sonnen chief marketing office Philipp Schroder said in a statement. “With our sonnenBatterie we can offer them a real choice of becoming independent and using clean power for an affordable price.”

Sonnen says its smart controls, via a “self-learning algorithm” and data from the weather bureau pcan identify the best time to start charging and, even with no- one at home, can activate appliances like washing machines.

Sonnen began selling battery storage systems in Germany, and has sold more than 10,000 systems to date. It plans to play on its “premium”, made-in-Germany branding.

“It has an outstanding ‘Made in Germany’ quality that ensures that a household’s investment in becoming independent of expensive grid power is sustainable and safe,” said Chris Parratt, the company’s country director in Australia, in a statement.

The company says the composition of the lithium-ion-phosphate battery gives it a long life in terms of its competitors, with 10,000 charge and expend cycles.

    It’s premium brand and made in Germany reputation, will be severely let down by the partnering with Australia’s Worst Solar company. Doesn’t make sense really ?

    By next year all of these batteries will be competing on price. I think that I will wait a bit and see where we are then.

      Good thinking!

      Curious to know. Given that fully installed solar batteries are over the $ 1000/ KWH mark and this is too expensive, otherwise you, like myself, would not wait for prices to drop, what would be your Price- point before seriously committing to buying a solar battery array? Mine would be in the $250 to $300/KWH range ( fully installed of course).

        As my Time-Of-Use peak vs base rates differ by US$0.30/kWh, I probably will not buy to kill my peak until the per kWh cost gets down to about half that difference for my grid usage (about $750/kWh installed). At about US$0.05/kWh per cycle I will seriously consider going off-grid. That does translate well to the price points you are looking at assuming a 5000 cycle guarantee. ($250 / 5000 = $0.05)

    Be interesting to see how this all pans out in a year or two. We have 5gw of solar with additional .75gw estimated for 2016. My guess is we will see 100mw in batts this year and 300mw next.

    Hardly giving it to the network but from little things big things grow.

    I am glad I have my stuff sorted and installed 20kWh LiFePO4 for 10k$… beat that.

    • trackdaze 5 years ago

      Do tell

      • MaxG 5 years ago

        Since it is Low voltage, you can build it yourself. Get 16 LiFePO4 cells 3.2V 400Ah, 16 BMS modules from ev-power as well as their 400A BMS (modified with proper DC relay); a 250A (self-extinguishing) fuse, and 70mm2 cables and lugs. Stick it into an aluminium tradie box, and hook it up to an inverter/charge like the Selectronic SP-PRO (which I have got), and your done! 🙂

          Lovely Installation.
